The latest poll from Ipsos shows why it’s time to ditch the Additional Member System used to elect MSPs.
The company’s latest survey grabbed the headlines for placing Reform second, behind the SNP, on the constituency vote. Neither Nigel Farage’s rising party, nor UKIP before it, have even won seats at Holyrood so this result would be a seismic shift in political behaviour.
However, beneath the headlines of Reform’s surge, the polling numbers alongside seat projections tell a different story. One of a creaking electoral system past its best.
The poll puts the SNP on 35% and 28% for constituency and list vote shares respectively. According to projections by Ballot Box Scotland, that is estimated to give the party 60 seats. That’s almost 47% of seats available.
The difference is staggering. Under AMS where seats are meant to match list vote share, BBS projects that the party would likely win around 40 seats. That’s still above the 28% of seats they would be entitled to under a fully proportional system (usual caveats about different voting systems impacting voting intention).
The biggest difference here is with the SNP. The party has lost significant support since 2021 but benefits from a fragmented unionist vote, with four parties competing for anti-independence voters – namely the Lib Dems, Labour, Conservatives and Reform.
BBS projects Scottish Labour would win 19 seats if Scotland voted like this. That’s 4 fewer than if a more proportional AMS was used (23).
Reform lose out the most, projected to win 6 short of the 23 they would win in a “better AMS”.
The Greens are projected to win 17 seats (AMS ideal: 21), the Conservatives 11 (AMS ideal: 14) and the Lib Dems 5 (compared to 8 under AMS ideal).

This result would mark a major shift in Scottish party politics, and a major decline in support for the Westminster duopoly. But that change risks not being fully shown in terms of seats.
Next year marks 27 years of devolution and the sixth Scottish election. Wales has reviewed and changed its fairly disproportional voting system for something somewhat better. Scotland’s sixth parliament should legislate to do the same.

The risk of 2021 was Alex Salmond’s Alba gaming the system to win a disproportionate independence supermajority. As we know, that outcome never emerged. This time, the threat of a seriously disproportionate election result comes from something much more likely. If the results in May look something like this, let’s hope they’re a wake-up call to our new legislators.
